James,
In comment #6 you mentioned that you experience no btrfs slowdowns in a
virtualized environment. That's probably because btrfs is running on an
underlying filesystem, with a separate caching mechanism by the physical
hard disk and host OS's handling of your disk. The net effect seems to
I can confirm the same issue; installation via the alpha 2 32bit
alternate media takes ~2 hours when installing to a btrfs partition,
compared to ~15 minutes to ext4. I'm not sure that system specs are
necessary, because I don't think this is a bug (or if it is, it should
be addressed upstream).
Igor, Andy others,
I've done some investigation and found that it's not necessary to build
ata_generic.ko as a module. From the kernel-parameters.txt documentation
I noticed it says the following:
Module parameters for modules that are built into the kernel image
are specified on the kernel
Petar,
You clearly implied that I was misinterpreting my results in the first
sentence of comment #37. In comment #59, I acknowledged that your system
appears not to have the same memory leak issue; as I said, your
allocation increases /and/ decreases, unlike my own. I asked for
evidence simply
Martin,
Although the initial feedback from most people seems to indicate that
the proposed update fixes the issue, I haven't seen anybody post output
that would positively confirm the leak as being fixed (in other words,
that the GEM object byte allocation is actually reducing when

Petar Volkovski,
What you did in comment #51 is just another variation of the testcase in
the bug description that others have been performing (and that you
insist does not represent a memory leak).
Your output differs from mine in that the GEM allocation increases *and*
decreases. I have never
Unfortunately, this proposed X server update has not resolved the
problem on my system. I'm using a stock Ubuntu Lucid installation,
compiz enabled, and with the proposed X server update.

Update on comment #33:
I managed to have a quick word with David Airlie, and he told me that
the radeon driver does not report the pinned/pin/gtt values, so that's
not an issue.
Here are some results from kernel 2.6.34-rc5 with the latest xorg-edgers
packages [1]:

Using kernel 2.6.32-21-generic and xorg-edgers packages:
After just 10 minutes uptime the slowdown has occurred, with a lower
object bytes count than before. Here is the output at the point in which
the slowdown became noticeable:

Final test: kernel 2.6.34-rc5 + stock drivers + proposed X server
update.

Peter Velkovski,
Thanks for the suggestion, but on my system - even if I close all
applications on the running X server - the GEM object bytes value
*never* decreases. Freeing the pagecache, dentries and inodes (as you
suggest) makes no difference at any point.
The only way to reduce the
While the problem is related to GtkRange::trough-under-steppers = 1 in
the theme gtkrc, let me clarify that this is a GTK widget style
property, and *not* a Murrine engine option [1].
XULRunner-based applications (such as Firefox, Thunderbird, etc.) seem
to ignore some (or all?) GTK widget style
I also forgot to mention: OpenOffice.org also does not seem to respect
style properties; this is hardly surprising, since it's all-round GTK
support is quite poor.

I noticed that you re-modularized the PATA/SATA drivers in kernel

I'm confirming the problem, which appears to visually affect many/all
applications.
With the latest update:-
-Video playback stutters every 1/2 second
-Dragging a window is noticeably slow (especially when compositing is disabled)
-Aislerot Solitaire - dragging cards causes ghosting effect
I've noticed this problem as well (with the radeon and intel drivers on
separate machines). My impression is that the GtkProgressbar widget is
causing the excessive CPU usage (at least during the installation of
updates).
